constant expression required

在编译app时，出现"constant expression required"错误通常是因为在定义数组大小或在使用枚举类时，要求使用常量表达式作为大小或值。这意味着在编译时，必须将表达式求值为一个常数，而不能是变量或非常量表达式。这是因为在编译期间，需要确定数组的大小或枚举的值。如果你在定义数组大小或使用枚举类时遇到了这个错误，你需要确保所使用的表达式是一个常量表达式，而不是一个变量或非常量表达式。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
